I need your help! I need to know why when I place a new acro, the polyps are fully expanded. Then within a few days they retract to where I can only see the tips.
My monti's and pocilliporas are out in full glory.
I am getting growth from all.
My parimeters are all fine:
14 a bit high
1200 to 1400
phos 0 according to test kit
nitrate is around 10-20, drops down with water changes every two weeks at 15%
I do have a flameback pigmy angel but have never seen it peck at the sps
Help please or am I just crazy?
